Third-party developers can add functionality to Apple's QuickTime video player through plug-ins called QuickTime components. These allow QuickTime users to view a wider variety of video files, use special features and encode videos in additional formats. Apple hosts a webpage that links to the download locations for third-party QuickTime Components. Users must download the desired components separately from each developer's website and install them individually.

Step 1

Go to the QuickTime Components webpage (see References). Click on the component you want to download; this will link you to the appropriate website. Click on the download link and press the "Save" button in the onscreen prompt.

Step 2

Double-click on the .dmg file for the component to mount it on your Desktop.

Step 3

Click on the your hard drive under "Devices" in the Finder window. Double-click on the Library folder. Open the QuickTime folder. If there is not a QuickTime folder, go to the "File" menu and select "New Folder". Name the folder "QuickTime".

Step 4

Open another Finder window by pressing Command-N. Highlight the disk image you mounted in Step 2. Click on the component file, drag it to the QuickTime folder and drop it.

Step 5

Double-click on the "Pref App" file if the disk image contains one, and confirm the preferences in the onscreen prompt.
